SUMMARY
Conventional X-ray imaging utilizes the photoelectric effect, while Computed Tomography (CT) employs Compton scattering due to the energy levels involved. At higher energies, specifically around 1 MeV or higher keV, Compton scattering becomes the dominant interaction mechanism for photons. This choice is strategic, as the energy beam is selected to optimize the imaging process, with beam hardening techniques applied to eliminate lower energy photons that do not contribute effectively to image quality.
